These valves likewise forni nopart of the present invention, and as there are various other well knownconstructions equally adaptable,

foruse in connection with machinesy of this sort, the detailsthereof donot require to be further described.

The rotatable parts of the machine, which comprise tubular shaft B andthe parts just referred to as being supported thereby, as also thebottle lifts() presently to be described, are given their. properrotativeI tably secured to shaft B. Such spider andl the bottle liftsthus carried thereby ofcourse rotate with the-general frame of themachine as though an integral part therewith so that the lifts andvalves alwaysr remain in such alinement.A Each plunger C at its upperendis provided with a platform or shelf o adapted to receive and holdabottle of the particular size being filled, which shelf may, if desired,be resiliently supported upon the plunger proper. Reciprocation of theplungers is derived, as has been previously indicated, from a cam,designated D, Fig. l, through a series of bell-cranks or levers D ofwhich one is obviously required for each plunger. Said cam, the form ofwhich is better shown in Fig. 23, is ixedly secured to the upwardlyextending portion a of the machine base and has its contacting face sodisposed as to always bear squarely against the short arxns'rZ of thebellcranks as the latter are oscillated inthe course of the travel ofthe frame around the axis of the'y machine. A connecting rod Z2preferably joins the outer or long arm D of each crank with thecorresponding plunger. In certain types of machineJ such connection ismade direct. Such long arms of the cranks are extended in my presentimproved construction, a short distancebeyond the point of attachment ofthe connecting rods therewith, and, attached to each plunger supportingarm c so as to lie adjacent to the position occupied by such crank armin its upper position, is a depending bracket E in which is mounted acatch e normally held by a dat spring e or by gravity, in position toengage the projecting portion fa of the hell crank arm and prevent thesame from dropping. When thus held, the cam is obviously not needed andits bearing face is hence cut away throughout substantially all thatp0rtion of its circumference. that corresponds with the raised positionof a bottle lift (see Fig. 3). When, however, the recessed portion Zt ofthe cam, corresponding with the lowered position of the lift, isreached, in the course of travel. of the lever about the same, the catchrequires to bevv withdrawn, and to this end, I .provide'a trip e2conveniently mounting the same on the upper end of a standard E that issecured to the machine base. The position of this trip relatively to thecam D is shown in the lfigure last referred to, from a reference towhich figure it will beseen that as any particular vbottle lift isbrought around adjacent thereto, the lower depending end of the catcheis engaged by the cam face of the trip e2, and the catch e7 on thecatchs innerv face, which engages with the projecting portion of thelever, is withdrawn from such engagement. The lower end of the catch,which is engaged by the trip, furthermore, bears a roller es in order toreduce. friction. Preferably the main actuating-cam D is formed so as toen'- gage with the short arm of a bell crank just before the catch e isthus engaged by the trip position and the catch now being past the tripe2 again becomes effective and engages andlholds the lever, togetherwith the plunger, from dropping. As a result of the foregoingconstruction, itwill be Obvious that frictional vcontact between thebell-cranks and the main actuating cam Aoccurs only during therelatively short time that the latter is utilized in lowering andraising the plungers constituting the bottle lifts. During the entireremaining portion of their travel, n0 contact with the cam is requiredand as a matter of fact, such cam may be entirely cut away throughoutall but the portion just referred to, so as to assume the form shown inFig. f

It will be obvious that my improved device for relieving the frictioninvolved in having the bell-cranks contact With the main actuating camthroughout the whole course of their travel, is equally adaptable tothat form of the machine in which such bell cranks are directlyconnected with the plungenas also to the earlier type. of fillingmachine in which the lifts. are directly raised and lowered by theoperation of a ll li Lonsdale cam track that contacts withtheir lowerends. This latter form of machine with my improvements incorporated, isillustrated in Fig. 8, where the plungers C2 ol the bottle lifts, itwill be seenterininate in rollers cL that are adapted to run along .icircular cam tracli'l)2 suitably disposed lo engage therewith. This camtrack instead of extending entirely around the machine, however,consists only of the portions required to raise and lower the lifts,such lil'ts beingl held in their upper position during the remainder oftheir course oi travel by catches cl3 operating in exactly the sainefashion just described and released by a trip el stationed adjacent tothe point where the lowering ol. the lifts is designed to commence.

lt has been indicated above that in place of a spring forreiulering thecatches operative gravity operated means may be substituted; thus forexample a counter-weight e3 integral with a pivoted catch el is shown inFig. 7. The catch el in this case depends below its pivotal axis, justas does catch c in the torni previously described, and so rcquires to beoscillated in the saine direction. The trip e5 here provided (shown indotted outline only) is accordingly disposed to engage the counterweightfrom below. A variant form oit spring catch is also illustrated in Fie'.7, where the catoL assumes the forni of a adially reciprocable plungere, normally retained in its inner operative position by a spring cm,while a deliending projection cu 'on its rear end both serves as a stoptor such plunger and as means whereby the trip may engage therewith, aswill lbe readily understood.
